UNITED STATES PATENT OFFICE.

JOHN W. RUSSELL, OF CANAAN, CONNECTICUT.

VGAGE-KNIFE.

SPECIFICATION forming part of Letters Patent N o. 3G8,855, dated August23, 18817.

Application filed May 17, 1887. Serial No. 238,517.

T @ZZ whom it may concerm .Be it known that I, JOHN W. RUssELL, ofCanaan, in the county of Litchfield and State of Connecticut, haveinvented certain new and useful Improvements in Bread-Knives; and I dohereby declare that the following is a full, clear, and exactdescription of theinvention,

w which will enable others skilled in the art to bread-knives inwhich aguide or guard bladeis secured parallel to the blade of the knife and ata distance from it equal to the thickness desired. for the sliced bread,the said blade serving to guide the cutting-blade through the bread andto regulate the thickness of the slices of bread cut; and it consists inthe iml proved construction and combination of parts of such a knife inwhich the guideblade may be adjusted at different distances from thecutting-blade,allowing slices of different thickness to be cut, ashereinafter more fully described and claimed In the accompanyingdrawings the numeral I indicates the cutting-blade, which is secured inthe handle 2 and is of the usual construction, and this blade is formedwith two perforations, 3 and 4, countersunk upon one side of the blade,as shown at 5, into which perforations the tenons or shanks 6 of twouprights, 7, may be inserted and riveted, the countersinks of theperforations admitting of the Shanks being riveted. The uprights orposts are provided with flaring shoulders or collars 8 at their innerends, bearing against the face of the blade, and the inner facing sidesof the posts are formed with series of registering notches 9 at suitabledistances from each other.

A guideblade or guard, l0, of the same Width as the cuttingblades, andhaving its (No model.)

ends slightly thinner than its middle, is se-A cured with its roundedand roundedly-notched ends Il in the registering notches of the posts,the said posts having sufficient yield or spring in them to admit of therounded ends of the said guide-blade being inserted between them andslipped into the desired set of notches.

It will now be seen that when the guideblade is secured into one set ofnotches the cutting-blade may only cut one thickness of slice equal tothe space between the two blades, and that when the guide-blade bearsagainst the outer side of the slice the thickness of the slice will beeven at all points, as the blade is parallel with the cutting-blade, andby bringing the guide-blade to bear at each slice against the outer sideof the slice being cut the bread may be cut into slices of equalthickness and of an even thickness at all points. The thickness of theslices may be regulated by adjusting the guide-blade in sets of notchesnearer to or farther from the cutting-blade, and it will be seen thatany bread-knife or common knife may be converted to this construction bysecuring the posts in the blade and adding the guide-blade.

By having the perforations in the cuttingblade countersunk and havingthe uprights provided with the collars and riveted in the countersunkperforations the cutting-blade is in no manner weakened by theperforations, and the posts will remain perfectly solid in theperforations.

Having thus described my invention, Iclaim and desire to secure byLetters Patent of the United States- In combination with a knife-blade,two posts having notches in-their facing sides and secured in one sideof the blade near the ends of the same, and a guide-blade having itsnotched ends secured in the registering notches of the posts, as and forthe purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnessesh JOHN W. RUSSELL.
